Answers before the quotation.

Five planning tools built from the way we actually scope and interpret work. They are indicative aids — never a substitute for a ground investigation and a signed design — but they will get you to a sensible number today.

Tool 01

Ground investigation scope builder

Size an investigation against your structure and footprint — boreholes, depth, metreage, trial pits, laboratory and field duration.

Tool 02

SPT → allowable bearing pressure

Meyerhof settlement-based estimate for granular soils, or an undrained estimate for cohesive soils with a factor of safety of three.

Tool 03

Plasticity classifier

Plots your liquid and plastic limits on the Casagrande chart and returns the USCS group, position against the A-line and swell potential.

Tool 04

Resistivity, corrosivity & earthing

Converts a Wenner resistivity measurement into a soil corrosivity class and an indicative earth electrode requirement. The same check we run on transmission and pipeline projects.

Tool 05

Pressure unit converter

Bearing pressures move between kPa, kg/cm² and t/m² depending on who drew the design. Convert once, quote once.

Next step

From a number to a crew on site.

These tools tell you roughly what the work looks like. The request-for-quotation builder turns that into a scope we can price — and it carries your scope-builder output straight across.

  • Structured RFQ in four short steps
  • Send by email, WhatsApp, or print for your file
  • Automatic RFQ reference number

Every output on this page is a planning estimate produced from published correlations. Correlations are not designs: they assume uniform strata, exclude organic, collapsible and expansive special cases, and carry no site verification. Foundation, earthing and pavement designs must be based on a ground investigation and signed by a qualified engineer.

We make it happen

Stop estimating. Start measuring.

Send us the scope you just built and we will price it, programme it and put a crew on it.
